Description

DESCRIPTION

Wind power installation with current conduction means previously mounted on the tower

The invention relates to a wind power installation with a tower constructed from several tower segments, with a generator arranged in the area of the head of the tower, with a power module arranged in the area of the foot of the tower and with current conduction means for the transmission of current from the generator to the power module, for example, document WO-A-01/77527.

10 The electrical power module of a wind power installation, which comprises electrical units such as transformers, distribution cabinets, if necessary, inverters, medium voltage installation, low voltage distribution, etc., is arranged in the installation of known wind power, below the level of the generators and, often, in the area of the foot of the tower of the wind power installation. For these or for some of these components, in most cases a small building is planned outside the wind power plant. In order to transmit the electrical energy generated by the generator arranged in the area of the tower tip inside a gondola to the power module, current conduction means are provided that run mostly inside the tower and are configured in the form of cables. These cables are placed in the tower after it is lifted. This is an expensive procedure since the cables must be installed all the way up the tower in an independent work stage. In addition, this work stage 20 depends on the previous assembly of the tower.

The present invention is based on the objective of indicating a wind power installation that can be lifted more simply and, therefore, more favorably and quickly.

This objective is achieved according to the invention by means of a wind energy installation according to claim 1.

Therefore, the segments of the current conduction means are pre-assembled and preferably placed in the tower segments before the tower composed of the individual tower segments is lifted. Therefore, it is no longer necessary to lay cables costly through the tower after it has risen to electrically connect the generator and the power module to each other. Thanks to the measures according to the invention, the total lifting time of the wind power installation can be shortened and the lifting costs can be reduced without taking into account any technical disadvantage.

Advantageous configurations of the wind power plant 35 according to the invention are indicated in the dependent claims. It is preferably provided that the segments of the current conduction means are only fixedly connected with the corresponding tower segment in one area, preferably in the upper zone in the assembled state. This fixation with the tower segment preferably takes place before the tower is lifted, so that the tower segments are already pre-assembled, including the segments there fixed to the current conduction means. Since the segment of the current conduction means is only fixedly fixed to the tower at one point, it is suspended in a fixed but mobile way between certain limits in the inner wall of the tower segment and, therefore, can still be oriented to connect in the simplest and best possible way with the following segments of the current conduction means of the next tower segment.

45 However, additional fasteners can also be provided for additional fixing of the segments of the current conduction means within the tower segment with which the segments of the means of connection are fixedly connected. conduction of current before or after the lifting of the tower to fix it as well as possible.

50 By means of the use of conductive rails as current conduction means, to overcome the parts protruding from the inner wall of the tower and for connecting segments of conductive rails, flexible connection rails are provided. These are used after lifting the tower to join segments of conductive lanes if they do not arrive directly next to each other or in the event that gaps or other obstacles must be overcome between the segments of the conductive lanes, for example, a flange in the Lane segment of the 55 tower.

On the one hand, to protect the maintenance personnel from contact with the conductive lanes when climbing the tower through its interior space and guarantee electrical isolation and, on the other hand, to protect the current conduction means from damage, provided a protection plate, which, for example, is fixedly connected with the inner wall of the tower and totally protects the current conduction means from the

Contact with these. Likewise, this protective coating can be divided into individual segments which also, like the segments of the current conduction means, are previously mounted on the tower segments. This results in an additional shortening and simplification of the wind power plant survey.

Next, the invention is explained in detail by means of the drawings. They show:

Figure 1 a representation of a wind power installation according to the invention,

10 Figure 2 a detail of such a wind power installation with two tower segments, and

3 shows a perspective representation of conductive rails provided according to the invention.

The wind power installation 1 according to the invention shown schematically in Figure 1 has a tower 2 with a base 3, a gondola 4 rotatably placed in the area of the tower tip, as well as a power module 7 arranged in the area of the foot of the tower, for example, in a separate house. Inside the gondola 4 a rotor is arranged rotatably with respect to a horizontal axis with several rotor blades 5, as well as an electric generator 6. By means of the wind forces acting on the rotor blades 5 the rotor is rotated and generator 6 is operated for the production of electrical energy 20.

For the transmission of the energy generated by the generator 6 to the power module 7 which has numerous electrical units, namely a transformer or, if necessary, an inverter for the additional treatment of the electric current, before it is supplied to the network or is transmitted to a consumer, are provided according to the invention conductive rails, preferably two conductive rails, placed in the wall of the interior space 25 8 of the tower 2 by fixing elements 10. These are electrically conductive and electrically connected with the generator by means of a cable 11, as well as, by means of a connection conduit 12 that preferably runs through the base 3 and the subsoil, with the power module 7.

The conductive rails 9 are rigidly configured and are preferably composed of individual segments 30 of conductive rails as shown in detail, for example, in Figure 2. There are shown two tower segments 21, 22 from which preferably lift tower 2. These tower segments 21, 22 may be made, for example, of steel or concrete.

These tower segments 21, 22 are pre-assembled and coupled at the installation site of the wind power installation to form the tower. To further shorten the lifting time and simplify the work and thereby also reduce the costs of the entire wind power installation, preferably the conductor rail segments 91, 92 are also fixedly fixed before lifting the tower 2 at the corresponding points of the individual tower segments 21, 22. Preferably, the fixing of the conductor rail segments 91, 92 only takes place in the upper area of the corresponding tower segment 21, 22 by means of a fixing device 40 10, while the remaining part of the conductor rail segment 91, 92 can move even between certain limits to simplify the union with the successive segments of conductive lanes. Thanks to this design, relative movements between the tower 2 and the driving rails 91, 92 can also be compensated, for example, as a consequence of different expansion coefficients. However, it may also be provided that other fasteners 14 that guide the conductor rail segments 91, 92 are used throughout their length. To this end, the cross section of the opening for segments 91, 92 of the conductor rails may be sized in the fasteners 14 greater than the cross section of the conductor rail segments 91, 92 themselves. In this way, a relative movement of the conductor rail segments 91, 92 in the clamping elements 14 is possible and at the same time the conductor rails 91, 92 are guided and their movement capacity is limited.

fifty

To electrically connect the conductor rail segments 91, 92 and, in addition, overcome parts that eventually occur and protrude into the interior space, such as, for example, tabs 211, 212 present in the lower and upper edge of the segments of tower 21, 22, insulated flexible connection rails 13 are used whose shape can be modified manually by placing them in the two segments of conductive rails 55 91, 92. Thanks to these connection rails 13, dilations or contractions of the materials can also be compensated, by For example, due to temperature fluctuations.

A perspective representation of two parallel conductor rail segments 911, 912 is shown in Figure 3. These are fixedly screwed to the clamping device 14 by means of screws 15. In addition, insulating means may be provided to insulate the segments of conductive rails 911, 912 with respect to the

clamping devices 14. Alternatively, of course clamping devices 14 may also be made of insulating material. The clamping device 14 itself is fixedly screwed with the inner wall of the tower segment.

5 For protection against the contact of the conductive rails 911, 912 during the operation of the wind power installation, a protective plate 16 is also provided which, like the conductor rails segments 911, 912, can already be mounted on the individual segments of the tower before the lifting of the tower 2. By means of a guide rail 17 which can be made, for example, of a hard rubber, on the one hand, this protective covering is fixed and, on the other hand, Isolates in front of the tower segment. However, to fix the protection plate 16, other means that are not shown can also be provided.

In addition, other devices such as plugs, lamps, etc., can be placed in and / or within these protection plates 16 provided as protective coverings, so that they can be pre-assembled easily. In addition, especially an assembly of these devices in the protective coating 16 prevents a compromised assembly in the inner wall of the tower and, therefore, leads to a reduced risk of damage, for example, due to objects that fall during and after the lifting of the tower.
